Renewable Energy

Renewable resources of energy are a growing part of our energy mix. Several of the states where Xcel Energy operates have some of the most stringent renewable portfolio standards in the U.S., and we support these standards. Our renewable energy portfolio includes wind, hydroelectric power, solar and biomass that comes from our own generating facilities and from power-purchase agreements. These sources provide clean, cost-effective energy to our customers, and they support our emissions-reduction goals.

2009 Renewable Energy Portfolio (in MW)

	Wind	Hydro	Solar (AC)**	Biomass	RDF/Landfill	Total
NSP	1,265	277		193	115	1,850
PSCo	1,258	88	40		3	1,389
SPS	653*					653
Projected by 2020	5,040*	380	580	210	120	6,330
*SPS wind energy totals include 443 MW from long-term contracts and 210 MW of required purchases from qualifying generating facilities; no wind from these qualifying facilities is included in the 2015 forecast. ** In 2009, we began reporting and tracking solar energy on our system in alternating current or AC megawatts to be consistent with how we report and track energy from all other generating sources. Prior to this, we used direct current or DC for solar energy, as it is commonly used in the solar industry.
